Python 2.7.10 错误“从 urllib.request 导入 urlopen"没有模块命名请求 [英] Python 2.7.10 error "from urllib.request import urlopen" no module named request

问题描述

我从 github 打开了 python 代码.我假设它是 python2.x 并在我尝试运行它时出现上述错误.从阅读中我看到 Python 3 贬低了 urllib 本身，并用包括 urllib.request 在内的许多库替换了它.

看起来代码是用 python 3 编写的(感谢知道的人的确认.)在这一点上，我不想转移到 Python 3 - 我还没有研究它会对我现有的代码做什么.

认为Python 2 应该有一个urllib 模块，我在Google 上搜索(使用python2 urllib 下载")并没有找到.(它可能隐藏在许多答案中，因为 urllib 包含下载功能.)我查看了我的 Python27/lib 目录，但没有在那里看到它.我可以获得在 Python27 上运行的这个模块的版本吗?地点和方式?

解决方案

尝试使用 urllib2:

https://docs.python.org/2/library/urllib2.html

这一行应该可以代替 urlopen:

from urllib2 import urlopen

在 Macbook Pro 上用 Python 2.7 测试

尝试发布指向相关 git 的链接.

I opened python code from github. I assumed it was python2.x and got the above error when I tried to run it. From the reading I've seen Python 3 has depreciated urllib itself and replaced it with a number of libraries including urllib.request.

It looks like the code was written in python 3 (a confirmation from someone who knows would be appreciated.) At this point I don't want to move to Python 3 - I haven't researched what it would do to my existing code.

Thinking there should be a urllib module for Python 2, I searched Google (using "python2 urllib download") and did not find one. (It might have been hidden in the many answers since urllib includes downloading functionality.) I looked in my Python27/lib directory and didn't see it there. Can I get a version of this module that runs on Python27? Where and how?

解决方案

Try using urllib2:

https://docs.python.org/2/library/urllib2.html

This line should work to replace urlopen:

from urllib2 import urlopen

Tested in Python 2.7 on Macbook Pro

Try posting a link to the git in question.
